mbob Playground for your computer
The same editor, installed. The code editor, the media library and the Python interpreter all live inside the app, so it opens and runs with no internet at all — and keeps itself up to date.
Fully offline
Editor, media and Python are bundled — nothing to download on first run.
Updates itself
New versions download in the background and install when you quit.
Same as the web
Your projects, snippets and templates work exactly as they do in the browser.
If your system warns you
These builds aren't code-signed yet. Windows may show a SmartScreen notice — choose More info → Run anyway. macOS may refuse to open the app — right-click it and choose Open, or allow it under System Settings → Privacy & Security.
Don't want to install anything?
The playground runs in your browser and works offline there too — install it from the address bar for an app-like window.
